Overview

1.25G DWDM SFP optical transceiver is a cutting-edge, ultra-long-haul solution engineered for high-capacity, inter-regional data transmission in Gigabit Ethernet and Fiber Channel networks. Leveraging Dense Wavelength Division Multiplexing (DWDM) technology, it operates on ITU-T grid-compliant wavelengths with ultra-narrow channel spacing, enabling unparalleled transmission distances of up to 160KM over single-mode fiber (SMF). This extreme reach makes it ideal for transcontinental backbone networks, submarine cable links, and large-scale telecom infrastructures requiring resilient, high-speed connectivity across vast distances.

Compliant with SFP MSA, IEEE 802.3, and DWDM standards, the module ensures seamless integration with existing systems while maximizing fiber capacity through multi-channel multiplexing. It incorporates advanced features such as enhanced forward error correction (FEC), low power consumption, and an extended industrial temperature range (-40°C to 85°C) for reliable operation in harsh environments. Integrated digital diagnostics monitoring (DDM/DOM) provides real-time performance insights and fault management.

The hot-swappable LC interface simplifies deployment, and its rugged design, coupled with high-sensitivity receivers (e.g., APD technology), ensures robust signal integrity over ultra-long spans. By minimizing the need for repeaters and amplifiers, this transceiver reduces operational costs and complexity. Combining DWDM’s spectral efficiency with unmatched reach, it delivers a scalable, future-proof solution for mission-critical, high-bandwidth applications demanding ultra-long-haul optical connectivity.
